Released versions of QNX 4 are strictly single-processor, whereas Neutrino, at the time of this second printing, has support for SMP on the x86 and PPC architectures at least. SMP is a great feature, especially in an operating system that supports threads, but it's also a bigger gun that you can shoot yourself in the foot with. For example, on a single-processor box, an ISR will preempt a ...

Since these large kernels contain the bulk of all OS services, the changes to support SMP are extensive, usually requiring large numbers of modifications and the use of specialized spinlocks throughout the code. QNX Neutrino, on the other hand, contains a very small microkernel surrounded by processes that act as resource managers, providing ...

Note: In QNX Neutrino 7.0 or later, we require that the hardware underlying ClockCycles() be synchronized across all processors on an SMP system. If it isn't, you might encounter some unexpected behavior, such as drifting times and timers.

In QNX Neutrino 7.0.1 or later, you can use SchedCtl() with the SCHED_CONFIGURE command to tune this behavior. In any case, the realtime scheduling rules that were in place on a uniprocessor system are guaranteed to be upheld on an SMP system. Kernel locking

QNX Neutrino RTOS by its very naming convention is a realtime operating system. Why is that important? An RTOS can help make complex applications both predictable and reliable; in fact, the precise control over timing made possible by an RTOS adds a form of reliability that cannot be achieved with a general purpose operating system.
